A top Iranian security official will arrive in Russia on
Tuesday for a three-day visit, Iran�s IRIBNews reported on Monday.

Supreme National Security Council Secretary Saeed Jalili is
due to meet with Russian President Dmitry Medvedev and other officials and
discuss bilateral relations, regional and international issues, the news agency
said on its web site.

It added that Jalili would be accompanied by Ali Bagheri,
deputy for foreign policy and security maters.

The report could not be immediately officially confirmed.

Mediators from the Iran Six, which includes Russia, are
currently discussing the transition from talks to new sanctions in response to
Iran�s refusal to fold its
controversial nuclear program.

Iran, which is already under three sets of United Nations
sanctions for refusing to halt uranium enrichment, recently announced plans to
build 10 new uranium enrichment facilities. Western powers suspect it of
pursuing an atomic weapons program.

The Iran Six are Russia, the United States, China, Britain,
France and Germany.

The mediators have long been trying to persuade Tehran to
halt uranium enrichment not only through sanctions but also in exchange for
economic and diplomatic incentives.

Iran Six envoys last met in New York on January 16 but
decided against immediate sanctions against Tehran in the hope to find new
political and diplomatic solutions to the problem.

Russia has a history of close ties to Iran, including in
nuclear energy through construction of the Bushehr power plant, but is seen as
having moved closer to the U.S. position on imposing new sanctions, while China
is still viewed as reluctant to change to a tougher course of action.
